Abstract:
Growth model is generally fitted by evaluating the mathematical parameters, a, b and c. In this study, the method of partial sums was used. For finding the mathematical parameters, firstly three partial sums were used and then N partial sums were used where N shows the number of data set. The purpose of increasing the partial decomposition is to guess the parameters of some growth models. The parameters for estimating the parameters of the best model function having the least error sum of squares could be used.
